  • Publication number: 20230404756
    Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet connector carried by a distal end of the catheter can be anchored to a superior surface of a mitral valve leaflet. A needle is axially advanceable through the leaflet connector and through the leaflet. A leaflet anchor having a leaflet suture can be advanced out of the needle to secure the mitral valve leaflet to the leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.

  • Patent number: 11666441
    Abstract: Methods and devices for transvascular prosthetic chordae tendineae implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet anchor having a leaflet suture is secured to the mitral valve leaflet. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae. The suture lock has a body with a suture path extending therethrough. A wall in the housing is movable to reduce the cross section of the suture path. A drive mechanism advances the movable wall to clamp sutures extending through the suture path, in response to rotation of a coupling on the housing.

  • Patent number: 10617523
    Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium to attach a leaflet anchor having a leaflet suture to a mitral valve leaflet. A ventricular anchor has a hub with a helical anchor and a core wire extending through the helical anchor. A radiopaque marker may be axially movably carried on the core wire, and a spring biases the marker in a distal direction. The marker is advanced proximally on the tissue surface relative to the helical anchor as the helical anchor is advanced distally into tissue to secure a ventricular suture to the ventricular wall. A leaflet suture and the ventricular suture may be tensioned and connected by a suture lock to form an artificial chordae.

  • Patent number: 10119443
    Abstract: The present invention relates to spark traps/arrestors that are unproved relative to those that currently exist. For example, the present invention relates to a spark arrestor/trap that comprises a plurality of features that allows sparks/embers to be more effectively extinguished. The spark trap/arrestor of the present invention has at least two of vanes, conical devices and u-turns that allows for sufficient oxygen and a tortured path that is sufficiently long so as to effectively extinguish sparks and/or embers that enter the system. Alternatively, the system relates to a spark arrestor that comprises all of vanes, conical devices and u-turns that allows for sufficient oxygen and a tortured path that is sufficiently long so as to effectively extinguish sparks and/or embers that enter the system. In one embodiment, the various parts of the spark arrestor can be separated allowing for easy cleaning of the system.
